Abstract
Description
Die vorliegende Erfindung betrifft eine Anordnung des Zwischenrads für den Rückwärtsgang bei einem Getriebe mit koaxialer Antriebs- und Abtriebswelle, insbesondere ein Stufenwechselgetriebe, und mit mindestens einer zusätzlichen Zwischenwelle für einen Nebenabtrieb gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to an arrangement of the idler gear for reverse gear in a transmission with coaxial input and output shaft, in particular a step change gear, and with at least one additional one Intermediate shaft for one Power take-off according to the generic term of claim 1.
Bei Stufenwechselgetrieben für Kraftfahrzeuge
mit koaxialer Antriebs- und Abtriebswelle werden üblicherweise
eine oder mehrere Rückwärtsga ngstufen über
ein sogenanntes Rückwärtsgang-Zwischenrad
zur Drehrichtungsumkehr realisiert, wie es beispielsweise im Rahmen
der
Alternativ kann das Rückwärtsgang-Zwischenrad auch in eine Verzahnung auf der Antriebswelle und eine Verzahnung auf der Vorgelegewelle als getriebene Welle eingreifen.Alternatively, the reverse gear idler gear also in a toothing on the drive shaft and a toothing engage on the countershaft as a driven shaft.
Alle heute bekannten Getriebe weisen für das Rückwärtsgang-Zwischenrad eine Position auf, welche die Lagerreaktionskräfte auf das Getriebegehäuse im Rückwärtsgang-Zugbetrieb möglichst gering halten soll und welche im Rückwärtsgang-Schubbetrieb (mit geringen Laufzeiten) in der Regel die größeren Lagerkräfte auf das Gehäuse aufweist.All gears known today show for the Reverse idle gear a position on which the bearing reaction forces on the gear housing in reverse gear train operation as possible should be kept low and which in reverse gear overrun (with low Terms) usually the larger bearing forces has the housing.
Nach dem Stand der Technik ist diese Position für das Rückwärtsgang-Zwischenrad wie folgt definiert:This is according to the state of the art Position for the reverse gear idler gear defined as follows:
Wenn man eine gedachte Ebene aufspannt, die durch die Drehachsen der treibenden und der Abtriebswelle geht, und diese Ebene horizontal ausrichtet, so dass die treibende Welle in Fahrtrichtung rechts von der Abtriebswelle liegt, dann befindet sich die Vorzugsposition für das Rückwärtsgang-Zwischenrad nach dem Stand der Technik immer unterhalb dieser Ebene.If you span an imaginary plane, the goes through the axes of rotation of the driving and the output shaft, and align this plane horizontally so that the driving wave is to the right of the output shaft in the direction of travel, then located preferred position for the reverse gear idler gear according to the state of the art always below this level.
In bestimmten Fahrzeugsegmenten erfolgt nach dem Stand der Technik der Antrieb von Nebenabtrieben durch eine zusätzliche Zwischenwelle, die ebenfalls in das Rückwärtsgang-Zwischenrad eingreift. Ein Beispiel für ein derartig aufgebautes Getriebe ist die Getriebebaureihe ECOMID der Anmelderin, wie sie beispielhaft aus Looman, Zahnradgetriebe, 3. Auflage, Springer-Verlag, Seite 263, bekannt ist.In certain vehicle segments occurs after the state of the art the drive of power take-offs by a additional Intermediate shaft, which also engages in the reverse gear idler gear. An example for one such gearbox is the ECOMID gearbox series the applicant, as exemplified by Looman, gear transmission, 3rd edition, Springer-Verlag, page 263, is known.
Ein Nachteil der beschriebenen Position für das Rückwärtsgang-Zwischenrad nach dem Stand der Technik ist, dass sich dadurch sehr große Lagerreaktionskräfte auf das Getriebegehäuse ergeben, wenn der Nebenabtrieb angetrieben wird. Diese hohen Lagerreaktionskräfte begrenzen das maximal zulässige Drehmoment und die zu erwartende Lebensdauer für den Nebenabtriebsbetrieb. Damit entsteht ein funktioneller Nachteil gegenüber Getrieben, bei denen der Nebenabtrieb beispielsweise direkt koaxial über die Vorgelegewelle angetrieben wird, wie das bei den Baureihen ECOSPLIT und ASTRONIC der Anmelderin der Fall ist. In diesem Zusammenhang sei darauf hingewiesen, dass die geforderte Lebensdauer für den Nebenabtriebsbetrieb um ein Vielfaches höher ist, als die geforderte Lebensdauer für den Rückwärtsgang-Betrieb.A disadvantage of the position described for the Reverse idle gear according to the state of the art is that very large bearing reaction forces the gearbox result when the power take-off is driven. Limit these high camp reaction forces the maximum allowable Torque and the expected service life for power take-off operation. This creates a functional disadvantage compared to gearboxes in which the Power take-off, for example, driven directly coaxially via the countershaft like the ECOSPLIT and ASTRONIC series from the applicant the case is. In this context it should be noted that the required lifespan for the power take-off operation is many times higher than the required Lifespan for the Reverse operation.
Der direkte Antrieb des Nebenabtriebes koaxial über die Vorgelegewelle ist jedoch in vielen Fällen, beispielsweise bei Mehrbereichsgruppengetrieben mit einer Nachschalt-Bereichsgruppe in Planetenbauweise nur möglich, wenn der Achsabstand zwischen Hauptwelle und Vorgelegewelle ausreichend groß ist. Ein ausreichend großer Achsabstand wiederum resultiert in entsprechend großen und schwer bauenden Getrieben mit entsprechend hohen Produktionskosten.The direct drive of the power take-off coaxial over however, the countershaft is in many cases, for example in multi-range group transmissions with a planetary-style range group only possible if the center distance between the main shaft and countershaft is sufficient is great. A big enough one Center distance in turn results in correspondingly large and difficult building gearboxes with correspondingly high production costs.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Anordnung des Rückwärtsgang-Zwischenrades bei einem Stufenwechselgetriebe mit koaxialer Antriebs- und Abtriebswelle und mit mindestens einer zusätzlichen Zwischenwelle für einen Nebenabtrieb anzugeben, welche die Lebensdauer des Nebenabtriebs optimiert. Insbesondere sollen große Lagerreaktionskräfte auf das Getriebegehäuse bei angetriebenem Nebenabtrieb vermieden werden.The present invention lies the task based on an arrangement of the reverse gear idler at Multi-step change gearbox with coaxial input and output shaft and with at least one additional one Intermediate shaft for specify a power take-off, which is the life of the power take-off optimized. In particular, large camp reaction forces are said to the gearbox when the power take-off is driven.
Zudem soll das maximal zulässige Drehmoment im Nebenabtriebsbetrieb erhöht werden.In addition, the maximum permissible torque increased in power take-off become.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Eine weitere Ausgestaltung gehen aus dem Unteranspruch hervor.This task is due to the characteristics of claim 1 solved. A further embodiment emerge from the subclaim.
Demnach wird vorgeschlagen, das Zwischenrad für den Rückwärtsgang oberhalb einer gedachten, durch die Achsen der treibenden Welle und der Abtriebswelle aufgespannten Ebene anzuordnen, wobei, bei einer gedachten horizontalen Ausrichtung der Ebene, die treibende Welle in Fahrtrichtung rechts von der Abtriebswelle liegt.Accordingly, the intermediate gear is proposed for the reverse gear above an imaginary, through the axes of the driving shaft and to arrange the output shaft spanned plane, wherein, at an imaginary horizontal alignment of the plane, the driving The shaft is to the right of the output shaft in the direction of travel.
Durch die erfindungsgemäße Anordnung des Zwischenrades für den Rückwärtsgang werden im Nebenabtriebsbetrieb deutlich geringere Lagerreaktionskräfte auf das Getriebegehäuse übertragen, so dass die Lebensdauer des Nebenabtriebsbetriebs signifikant erhöht wird. Zudem können im Nebenabtriebsbetrieb höhere Drehmomente übertragen werden.Due to the arrangement of the Idler gear for the reverse gear bearing reaction forces are significantly lower in the power take-off mode the gearbox transferred, so that the service life of the power take-off operation is significantly increased. You can also higher power take-off Torques transmitted become.
Des weiteren sind kompakte und kostenoptimierte Grundgetriebe mit kleinem Achsabstand und geringem Gewicht realisierbar, welche einen Nebenabtriebsbetrieb mit hohen zu übertragenden Momenten und großer Lebensdauer ermöglichen.Furthermore, compact and cost-optimized basic transmissions with a small center distance and low weight can be realized, which are a power take-off operation with high torque to be transmitted and long service life.
Die Erfindung wird im folgenden beispielhaft anhand der beigefügten Zeichnung, welche eine Schnittansicht einer bevorzugten Ausführungsform einer Anordnung gemäß der vorliegenden Erfindung schematisch darstellt, näher erläutert.The invention is illustrated below by way of example the attached Drawing showing a sectional view of a preferred embodiment of a Arrangement according to the present Represents the invention schematically, explained in more detail.
